| Abstract: | Members of the herpesvirus family mature at inner nuclear membranes, although a fraction of the viral glycoproteins is expressed on the cell surface. In this study, we investigated the localization of herpes simplex virus type 2 (HSV-2) glycoproteins in virus-infected epithelial cells by using a panel of monoclonal antibodies directed against each of the major viral glycoproteins. All of the HSV-2 glycoproteins were localized exclusively on the basolateral membranes of Vero C1008, Madin-Darby bovine kidney, and mouse mammary epithelial cells. Using a monoclonal antibody to HSV-2 gD which cross-reacts with HSV-1 strains, we could also localize HSV-1 gD on the basolateral membranes of Madin-Darby bovine kidney cells. These results indicate that these molecules contain putative sorting signals that direct them to basolateral membrane domains. |
